SB-555V "Auto Vajin"
This is Masked Rider Faiz's motorcycle, can transform into humanoid battle mode and move on it own thank to advance AI. When in battle mode, the back wheel will become hover ring and give it an ability to flight.While the front wheel will become "buster wheel", a wheel-shape Gatling launcher, which is powerful enough to kill Orphnoch monster. It's handle also work as "Faiz edge" an energy sword for Rider Faiz.http://www.thai.net/kuruni/capture/sb-913v_cycle.jpghttp://www.thai.net/kuruni/capture/sb-913v.jpg
SB-913V "Side Bassha"
Masked Rider Kaixa's motorcycle, the sidecar is ejectable. It's battle mode is much more powerful than Auto Vajin, as it's concept is a movable turret. (I'm not sure, but it may not feature advance AI like Auto Vajin.As Kaixa usaully control it manual.) The six exhaust pipe will become powerful 6-barrel photon cannon in battle mode.

I got these image from "The Art of Masked Rider". (Seem to be offcial translation.)

G3
Unlike most of Masked Rider from the serie.G3 isn't another lifeform, but a powersuit develope by Japan Police Department for fighting "Unknown" monster. Despite fact that G3 is 10 times more powerful than normal human and can equiped with various weapons, it still take lot of effort to beat a common Unknown. And G3 is consider the weakest Masked Rider from Kamen Rider Agito. It's later replaced by more powerful G3-X but still use in some operation.
For minor detail, on the left forearm of G3 is a "G-Com", a communicator device that can access to JPD's database.And the belt "G-Buckle" is display gauge of battery pack.
Accord to my knowledge, there are also G1 and G2 which are experiment model. G3 powersuit is improve by result of those experiment.

Guard Chaseser
This is G3's motorcycle and storage of G3's weapon. It's equiped with various type of sensor and infrared camera. While lineart use silver-blue colour scheme, it's white-blue in the serie.http://www.thai.net/kuruni/temp/triacceler.jpg
Tri Acceller
This electro magnetic stick is act like key for Guard Chaseser, and G3 can use it as weapon too. In that case, there are socket on left leg armor to hold it.
One thing to note, while storyline of Kamen Rider Agito seem to not relate to Kamen Rider Kuga. Guard Chaseser is actually named after Tri Chaseser and Beat Chaseser, Kuga's motorcycle. And all of them use Tri Acceller as key...

Phew! This one is quite late...My scanner just "play" with me again...

G3-X
While G3 seem to be impressive from human's point of view. It's actually ineffective against Unknown monster. So Osawa Sumika, developer of G3 develope new powersuit base on G3 called G3-X.
G3-X is much more powerful and advance than G3, one of new feature is the assist AI chip. This chip is suppose to help it's operator of G3 in combat. (think of ALICE from Gundam Sentinel.) But this feature is also G3-X's flaw. It will respond to operator at extreme scale. So G3-X's operator will be quickly exhaust, sometime he'll be faint and G3-X will move on it own.
That's what happen during the competition against V1 powersuit, a candidate to replace G3. Operator of V1 point his gun to G3-X and taunt. This make Hikawa Makoto (operator of G3-X) upset and suddenly faint, then the G3-X gone berserk. It beat V1 with just barehand then move out from test facility to destroy the detected Unknown with ease. It even attack Masked Rider Agito but soon collapse since Hikawa reach his limit.
Though Tsugami Shoichi (Agito) prove that he can operate G3-X without problem, it come from fact that he has pure heart (well, he's quite childish person and rarely take thing serious. He admit that he doesn't even think when fighting Unknown with G3-X, he "just do it".) G3-X is actually too perfect to be use by imperfect being like human. Osawa later replace the AI chip with modified one to resolve this problem.
The modified version of G3-X is slighly weaker, but it's still good enough to defeat several Unknown, include powerful one. Some of them amaze to see such power demonstrate from common human.
A GK-06 "Unicorn" electro-magnetic combat knife is add for close combat, it's hold on left thigh armor. I'm not sure if G3-X can use other of G3's armament, but GM-01 is a basic weapon.

GX-05 Kelberos (Sp? Cerberus?)
A multipurpose weapon. The barrel part is foldable in order to attached with Guard Chasser. This usaully use as powerful gatling gun that shoot hi-metal coating bullet. But also able to docked with GM-01 in order to shoot the high explosive grenade.(Image 2) This is most powerful weapon in G3-X's arsenal, the high explosive grenade has power equal to Masked Rider Agito's finish move "Rider Kick".

G4
Appear in movie "Project G4".
It is military model develope by Japan Defense Force, base on "stolen" data of G3-X.
Since it's base on "perfect" version of G3-X, it's more powerful than G3-X. The assist AI is even more dangerous, while it never gone berserk, it turn out that several operators die during G4's developement and only one survive. G4 even try to continue fight after the operator's death.
G4 was seen use only 2 weapons. First is a pistol similar to GM-01 and other is 4-rocket launcher that can kill several Unknown in one salvo.It wortha note that G4 is powerful enough to kill Unknown with just punching. Another dangerous feature of G4 is "Prediction System", when they capture Kirishima Mana (a girl who has high psychic power , heroine of the show) They hypnotize her and manage to use her power to generate a very accurate vision of incoming future, then transfer these information to G4. This is definity a very deadly ability, G4 can even fight Agito and G3-X in same time and win.
JDF has plan to mass produce G4 powersuit and do a commercial run. But the Prediction System bring large number of Unknown to developement facility. After this terrible attack, none of this project staff survive.

Ahh...my pity site...No, there is no translate version of those file. It just there because Thai.net claime to shut down any unuse account... Don't feel like miss anything, unlikely that there are something you never saw before. (Unless that period feature some G Generation's unit and I'm lucky enough to found some info.)

Phew! Here are some from Kamen Rider Black...(Sorry if some information seem to be lacking, it's quite long since I watched these series.)

http://www.thai.net/kuruni/capture/black.jpg
Masked Rider Black
First Maked Rider who doesn't has scarf.
His real name is Minami Kotaro, who were born on the day of a solar eclipse. When he kidnapped by evil cult Golgom, he was turn into cyborg, the Black Sun, implanted with Kingstone.
Actually, he suppose to desined to fight his stepbrother, Akizuki Nobuhiko who turned into Shadow Moon. And whoever survive from that battle shall become King of the Century, Golgom's ruler who will lead them to conquer this world.
However, Professor Akizuki manage to help Kotaro from brainwash (but not his son though). Now, Black Sun become Golgom's enemy...Masked Rider Black.

Professor Akizuki's son. Like Kotaro, he's turn into Shadow Moon but completely brainwashed by Golgom. Though Black doesn't want to fight him, he become Black's rival for most of the serie. (He also return in Kamen Rider Black RX.)

After fall of Golgom,Masked Rider Black is defeated by new enemy from other dimension called Crisis. However, when Kingstone was expose to sunlight, it turned him into more powerful form...Masked Rider Black RX.
While Black usaully fight without weapon. RX has ability to summon a sword "Revol Ken" from his belt. Later on,he also discover ability to transform in to other form, the Roborider and Biorider.

Those are super cool! The Roborider, Shadow Moon, and the later version of RX are my personal favorite. The other day I run into this site and they have a screenshot of the classic Kamen Riders lineup you mentioned. I never seen that episode, but it was cool to see them lineup like that. http://incolor.inebraska.com/stuart/riders/blackrx.htm

That site author also stated... "Kamen Rider Black RX seems to have been the least popular of the Kamen Rider series. " >_<

Thanks a lot for those images and back story, bring back some good memories and inspiration. :)

I would do scan of Faiz's and Kaixa's equipments and add more information later.http://img.photobucket.com/albums/v629/Kuruni/555_1.jpghttp://img.photobucket.com/albums/v629/ ... 5_axel.jpg
